Abstract: 692,476. Voice-frequency signalling. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. April 11, 1950 [May 5, 1949], No. 11982/49. Class 40 (iv). [Also in Group XL (c)] A voice-immune V.F. receiver incorporates frequency-selective amplifiers of the type in which negative feed-back is provided at all frequencies except that to be received, the said amplifiers being back-biased by a voltage obtained from a tuned guard circuit. The drawing illustrates equipment for responding to pure 600 and 750 c.p.s. signals, The input is applied via transformer TRA and valve VA to two signal-receiving circuits VC, VD and a guard circuit VB. Valve VC is provided with negative feed-back via a parallel-T circuit C12, C13, R13; R11, R14, C14 so chosen that the feed-back becomes zero at 600 c.p.s. Valve VD is connected in a similar manner to be responsive to 750 c.p.s. and valve VB is caused to be similarly responsive over the range 150 to 450 c.p.s., the output from this valve being rectified by the voltage-doubler MRA, MRB whose output back-biases VC, VD. The outputs from VC, VD are fed through voltage-doubler-rectifier circuits to valves VE, VF respectively whose anode currents operate the signal relays Y and X. As an additional safeguard the output from valve VA is connected via an aperiodic circuit to a further voltage-doubler circuit MRE, MRF whose output back-biases VE, VF. The input valve VA is run as a limiter, but to enhance the limiting effect and also to compensate the distortion introduced by this valve a silicon carbide non-linear resistor NLR is connected across its output. Specification 637,596, [Group XXXVI], is referred to.

IPC: A61K38/38
Filed: 1975-03-21
Abstract: An alcohol of the formula CH3-(CH2)n-OH, in which n is zero, 1 or 2, is added to human blood plasma, from which the coagulation factors have been removed, in the presence of albumin-stabilising substances and in the neutral pH range. Subsequently, chemical precipitation of the globulins takes place with breaking of covalent and secondary valent linkages of the globulin molecules while heating at 60 - 75 DEG C. After the reaction, the mixture is cooled, acidified to a pH of about 4 and the precipitate which has formed then removed. The albumin is then separated from the resulting solution with the aid of precipitants. The precipitation of the globulins preferably takes place in the presence of about 9% by volume of ethyl alcohol.

Title: Improvements in or relating to vehicle brakes
IPC: B60T13/48
Filed: 1931-04-29
Abstract: 377,317. Fluid-pressure brakes. CADNEY, W., No. 1 Stores Depot, Royal Air Force, Kidbrooke, London. April 29, 1931, No. 12623. [Class 103 (i).] Relates to vacuum braking-apparatus for motor road-vehicles of the kind in which, for applying the brakes, one end of a cylinder is connectible to the induction-pipe of the engine, or, for releasing the brakes and for lubricating purposes, to the engine crank-case. According to the invention the communications are controlled by a single-piston or like valve operable by a foot-pedal or equivalent member, which is adapted to apply mechanical braking simultaneously with the vacuum braking or when the engine is not running. In the case of a tractor and trailer vehicle the cylinder may be arranged on the trailer for braking the latter, and the control valve and mechanical brake on the tractor. In the arrangement shown in Fig. 9, a piston-valve 18 slidable in a casing 8 places a port 7 leading to the brake cylinder 1, Fig. 3, in communication either via a lateral port 10 with the induction pipe, or via an end-port 13 with the crank-case. The upper end of the piston rod 17 passes loosely through a bracket 192 on the brake pedal 19, while a spring 191 is disposed between the bracket and a shoulder on the piston-rod. In the normal position of the pedal 19 the brake cylinder is in communication with the crank-case ; when the pedal is depressed to the full line position, Fig. 9, the spring 191 moves the piston 18 to its extreme extent and the brake cylinder and induction pipe communicate, whilst on further depression of the pedal to the dotted position, the rod 17 slides through the bracket 192 and the mechanical brakes are applied to the single vehicle or tractor, as the case may be. Application of brakes from the piston 25 of the brake cylinder is effected by chain 24, lever 26, and rod 29 against the effort of a return spring 30. The opposite end of the cylinder 1 is fitted with a mushroom valve 31 having a loading spring 32 and designed to vent the cylinder when the braking effort exceeds a predetermined value. The braking arrangement may be combined with that described in Specification 369,702, the vertical operating push-rod referred to therein being connected through a bell-crank lever 43 and rod 42 to the brake rod 29, and a pin-and-slot connection 27, 28 between the lever 26 and rod 29 permitting independent operation by the two mechanisms.
